EA-18G Growler Electronic Attack Aircraft

The EA-18G Growler is an airborne electronic attack (AEA) aircraft which operates from either an aircraft carrier or from land-bases. The Growler has been developed as a replacement for the United States Navy EA-6B Prowler aircraft which entered service in 1971 and is approaching the end of operational life.

The Growler is a derivative of the combat-proven two-seat F/A-18 Hornet, the US Navy’s maritime strike aircraft. The aircraft missions are mainly electronic attack (EA) and suppression of enemy air defences (SEAD), particularly at the start and on-going early stages of hostilities.

The Growler aircraft has 11 weapon stations for carrying electronic mission systems and weapons and can then be used to carry out conventional strike missions when the requirements for EA and SEAD sorties are reduced.

EA-18G Growler programme and development

The US Navy awarded a five-year system development and demonstration (SDD) contract in December 2003. A contract for the first four production aircraft was signed in July 2006.

The Growler aircraft’s first test flight was successfully completed in August 2006. This was followed by delivery of the first two test aircraft to the USN in September and November 2006. The first production aircraft was delivered to the USN in September 2007.

The first operational aircraft was delivered to NAS Whidbey Island in June 2008 and operational evaluation began in October 2008 onboard the USS John C Stennis (CVN 74) aircraft carrier. The SDD programme will conclude with an initial operational capability in late 2009 when the first of ten electronic attack squadrons (VAQ) will begin EA-18G operations. Deliveries of 88 Growler aircraft are planned to conclude in 2013. In service the aircraft will carry out a range of missions including stand-off and escort jamming, surveillance and strike.

Naval Air Systems Command PMA-265 is the US Navy acquisition office for the EA-18G. The Boeing Company is the prime contractor and weapon system integrator and Boeing also leads the EA-18G Growler industry team. Northrop Grumman is the principal subcontractor and airborne electronic attack subsystem integrator.

The EA-18G Growler fleet will be based at Naval Air Station Whidbey Island, Washington.

The AMPD rugged display family consists of 5-by-5-inch forward avionics displays; 5-by-5-inch aft displays, and 8-by-10-inch avionics displays.

The AMPD replaces obsolete cathode ray tube (CRT)-based displays in legacy aircraft, and uses state-of-the-art active matrix liquid crystal display (AMLCD) technology.

The displays are full color, high density, and can be used during the day, at night, and with the night vision imaging system (NVIS). Of the AMPD family, the 5-by-5-inch versions are for the F/A-18E/F/G models, and the 8-by-10-inch versions are for the F/A-18F/G aft cockpit. The 8-by-10-inch model includes a direct digital video input.

The displays provide symbology, raster, and hybrid display formats, and support mono and full-color modes. Source militaryaerospace.com

The aircraft is equipped with HOTAS hands-on throttle and stick control and full digital fly-by-wire controls.

The aircraft is fitted with a helmet-mounted cueing system developed by the Rockwell Collins and Elbit joint venture company, Vision Systems International.

The HMCS provides ‘first look, first shot’ high off-boresight weapons engagement capability.

The system enables the pilot to accurately direct or cue the weapons against enemy aircraft while performing high-g manoeuvres. The pilot points his head at the target and weapons are directed to the target. Aircraft and mission data such as targeting cues and aircraft performance parameters are displayed directly on the pilot’s visor.

AARGM Fact Sheet OA Interim

In a surveillance-only configuration the Growler is armed with two AIM-120 air-to-air missiles for self defence. For stand-off jamming and escort jamming missions the Growler is armed with two AGM-88 anti-radiation missiles plus two AIM-120 missiles.

AGM-154 JSOW joint stand-off weapon

AGM-154 JSOW joint stand-off weapon (block 2 aircraft) low altitude release: 22 kilometres (12 nmi) high altitude release: 130 kilometres (70 nmi)

The AGM-154A (Formerly Advanced Interdiction Weapon System) is intended to provide a low cost, highly lethal glide weapon with a standoff capability. JSOW family of kinematically efficient, air-to-surface glide weapons, in the 1,000-lb class, provides standoff capabilities from 15 nautical miles (low altitude launch) to 40 nautical miles (high altitude launch). The JSOW will be used against a variety of land and sea targets and will operate from ranges outside enemy point defenses. The JSOW is a launch and leave weapon that employs a tightly coupled Global Positioning System (GPS)/Inertial Navigation System (INS), and is capable of day/night and adverse weather operations.

The JSOW uses inertial and global positioning system for midcourse navigation and imaging infra-red and datalink for terminal homing. The JSOW is just over 13 feet in length and weighs between 1000-1500 pounds. Extra flexibility has been engineered into the AGM-154A by its modular design, which allows several different submunitions, unitary warheads, or non-lethal payloads to be carried. The JSOW will be delivered in three variants, each of which uses a common air vehicle, or truck, while substituting various payloads.

AGM-154A (Baseline JSOW) The warhead of the AGM-154A consists of 145 BLU-97/B submunitions. Each bomblet is designed for multi-target in one payload. The bomblets have a shaped charge for armor defeat capability, a fragmenting case for material destruction, and a zirconium ring for incendiary effects.

AGM-154B (Anti-Armor) The warhead for the AGM-154B is the BLU-108/B from the Air Force’s Sensor Fuzed Weapon (SFW) program. The JSOW will carry six BLU-108/B submunitions. Each submunition releases four projectiles (total of 24 per weapons) that use infrared sensors to detect targets. Upon detection, the projectile detonates, creating an explosively formed, shaped charge capable of penetrating reinforced armor targets.

AGM-154B – Image: media.defenceindustrydaily.com

AGM-154C (Unitary Variant) The AGM-154C will use a combination of an Imaging Infrared (IIR) terminal seeker and a two-way data link to achieve point target accuracy through aimpoint refinement and man-in-the-loop guidance. The AGM-154C will carry the BLU-111/B variant of the MK-82, 500- pound general purpose bomb, equipped with the FMU-152 Joint Programmable Fuze (JPF) and is designed to attack point targets.

In a strike configuration the Growler is armed with two each of AGM-88 HARM missiles, AGM-154 JSOW joint stand-off weapon (block 2 aircraft) and AIM-120 air-to-air missiles. While carrying out active transmitting jamming, the block 2 aircraft has the capability of handing off target data to other airborne, land or surface attack platforms.

EA-18G and F/A-18F design

The EA-18G Growler aircraft is a derivative of the F/A-18F Super Hornet with structural changes and the installation of avionics and mission systems, increasing the empty weight by 800kg to 15,000kg and increasing the carrier landing weight by 1,350kg to 21,775kg.

One of the external visual characteristics is the wingtip air-to-air missiles on the F/A-18 Super Hornet are normally replaced by wideband receiver pods on the EA-18 Growler and the other hardpoints carry a mix of electronic warfare pods and weapons.

The aircraft construction includes a light alloy multispar wing and high-strength graphite and epoxy panels and doors. The major contractor Northrop Grumman manufactures the rear and centre fuselage sections and EADS CASA is responsible for the manufacture of structural components such as the fuselage rear side panels, horizontal tail surfaces, flaps, the leading edge extensions, the rudders and the speed brakes.

The aircraft has retractable tricycle-type landing gear. The Menasco main landing gear is single wheeled and turns through 90° to retract rearward into the wheel bays mounted in the engine air ducts. The aircraft has a Messier-Dowty twin-wheel nose gear. The nose of the aircraft is fitted with a catapult launch tow bar. An arrester hook is installed under the rear section of the fuselage.

Turbofan engine

The Growler is powered by two F414-GE-400 afterburning turbofan engines, supplied by General Electric. A titanium engine firewall is incorporated into the aircraft structure. The engines are rated to supply 62kN or 98kN with afterburn.

26500333_nRjJ6-MImage: from the web

The aircraft’s power is provided by two F414-GE-400 turbofan engines from General Electric. The engines are an advanced derivative of the GE F404 engines installed on the Hornet. The air inlets have been enlarged to provide increased airflow into the engines.

The engines each provide 22,000lb thrust, with afterburn giving a maximum speed in excess of Mach 1.8.

The structural changes to the airframe on the F/E variant of the aircraft increase the internal fuel capacity by 3,600lb, a 33% higher fuel capacity than the F-18C/D variant. This extends the mission radius by up to 40%.

F414-GE-400 turbofan engines

f414_01General Electric F414 turbo-fan engines

The General Electric F414-GE-400 is a 22,000-pound class afterburning turbofan engine. The engine features an axial compressor with 3 fan stages and 7 high-pressure compressor stages, and 1 high-pressure and 1 low-pressure turbine stage. At a weight of 2,445 pounds, the F414-GE-400 has a thrust-to-weight ratio of 9. The F414 is one of the U.S. Navy’s newest and most advanced aircraft engines. It incorporates advanced technology with the proven design base of its F404 predecessor – for example the F414 features a FADEC (Full Authority Digital Engine Control) system – to provide the Boeing F/A-18E/F Super Hornet and the EA-18G Growler with a durable, reliable and easy-to-maintain engine.
